Ultrasound guided pulmonary artery catheter insertion: An alternative to fluoroscopic guidance.

Pulmonary artery catheters (PACs) can provide extremely valuable objective data in select patients. They are usually advanced by floatation of balloon tip along the normal blood flow and their placement is confirmed under pressure waveform guidance. Imaging such as fluoroscopy is often employed in low flow states and in cardiac catheterization suite to reduce the failure rate and time to wedge; but is not readily available at bedside.

Impact of initial chemotherapy regimen on outcomes for patients with double-expressor lymphoma: A multi-center analysis.

Diffuse large B-cell lymphoma featuring overexpression of MYC and B-Cell Lymphoma 2 (double expressor lymphoma, DEL) is associated with poor outcomes. Existing evidence suggesting improved outcomes for DEL with the use of more intensive regimens than R-CHOP is restricted to younger patients and based on limited evidence from low patient numbers. We retrospectively evaluated the impact of intensive frontline regimens versus R-CHOP in a multicenter analysis across 7 academic medical centers in the United States.

HIV-associated Burkitt lymphoma: outcomes from a US-UK collaborative analysis.

Data addressing prognostication in patients with HIV related Burkitt lymphoma (HIV-BL) currently treated remain scarce. We present an international analysis of 249 (United States: 140; United Kingdom: 109) patients with HIV-BL treated from 2008 to 2019 aiming to identify prognostic factors and outcomes. With a median follow up of 4.

Autologous stem cell transplantation after anti-PD-1 therapy for multiply relapsed or refractory Hodgkin lymphoma.

Autologous stem cell transplantation (ASCT) can be curative for patients with relapsed/refractory Hodgkin lymphoma (HL). Based on studies suggesting that anti-PD-1 monoclonal antibodies (mAbs) can sensitize patients to subsequent chemotherapy, we hypothesized that anti-PD-1 therapy before ASCT would result in acceptable outcomes among high-risk patients who progressed on or responded insufficiently to ≥1 salvage regimen, including chemorefractory patients who are traditionally considered poor ASCT candidates. We retrospectively identified 78 HL patients who underwent ASCT after receiving an anti-PD-1 mAb (alone or in combination) as third-line or later therapy across 22 centers.

Burkitt lymphoma in the modern era: real-world outcomes and prognostication across 30 US cancer centers.

We examined adults with untreated Burkitt lymphoma (BL) from 2009 to 2018 across 30 US cancer centers. Factors associated with progression-free survival (PFS) and overall survival (OS) were evaluated in univariate and multivariate Cox models. Among 641 BL patients, baseline features included the following: median age, 47 years; HIV+, 22%; Eastern Cooperative Oncology Group (ECOG) performance status (PS) 2 to 4, 23%; >1 extranodal site, 43%; advanced stage, 78%; and central nervous system (CNS) involvement, 19%.

Intrauterine Pressure Catheter Use Is Associated with an Increased Risk of Postcesarean Surgical Site Infections.

Objective: This study aimed to determine if intrapartum placement of an intrauterine pressure catheter (IUPC) is associated with an increased rate of surgical site infections in women undergoing a cesarean delivery.

Study Design: This was a secondary analysis of the prospective observational Maternal-Fetal Medicine Units Network Vaginal Birth after Cesarean Registry. We compared patients with and without IUPC use.

Bazex syndrome in a patient with head and neck malignancy.

Bazex syndrome (acrokeratosis paraneoplastica) is an uncommon dermatologic condition associated with an underlying malignancy, most commonly squamous cell carcinomas of the head and neck. This article describes Bazex syndrome in a 56-year-old woman who presented with bilateral cervical lymphadenopathy and a mass at the base of her tongue.

Tissue damage volume predicts organ dysfunction and inflammation after injury.

Background: Multiply injured patients (MIPs) are at risk to develop multiple-organ failure (MOF) and prolonged systemic inflammation response syndrome (SIRS). It is difficult to predict which MIPs are at the highest risk to develop these complications. We have developed a novel method that quantifies the distribution and physical magnitude of all injuries identified on admission computed tomography scanning called the Tissue Damage Volume (TDV) score.

SHOCK VOLUME: A PATIENT-SPECIFIC INDEX THAT PREDICTS TRANSFUSION REQUIREMENTS AND ORGAN DYSFUNCTION IN MULTIPLY INJURED PATIENTS.

Multiply injured patients (MIPs) in hemorrhagic shock develop oxygen debt which causes organ dysfunction and can lead to death. We developed a noninvasive patient-specific index, Shock Volume (SV), to quantify the magnitude of hypoperfusion. SV integrates the magnitude and duration that incremental shock index values are elevated above known thresholds of hypoperfusion using serial individual vital sign data.

Database and Registry Research in Orthopaedic Surgery: Part I: Claims-Based Data.

The use of large-scale national databases for observational research in orthopaedic surgery has grown substantially in the last decade, and the data sets can be grossly categorized as either administrative claims or clinical registries. Administrative claims data comprise the billing records associated with the delivery of health-care services. Orthopaedic researchers have used both government and private claims to describe temporal trends, geographic variation, disparities, complications, outcomes, and resource utilization associated with both musculoskeletal disease and treatment.

The effect of pH versus base deficit on organ failure in trauma patients.

Background: Base deficit (BD) calculations are affected by trauma-related changes in circulating concentrations of anions after injury. In contrast, pH is a direct measurement that corresponds to hypoperfusion. We hypothesized that changes in pH would more closely correspond to organ dysfunction compared with changes in BD.

A review of trends in attrition rates for surgical faculty: a case for a sustainable retention strategy to cope with demographic and economic realities.

Background: Our aim was to compare trends in retention of academic surgeons by reviewing surgical faculty attrition rates (leaving academic surgery for any reason) of 3 cohorts at 5-year intervals between 1996 and 2011.

Study Design: The Association of American Medical Colleges' Faculty Administrative Management On-Line User System database was queried for a retention report of all tenure/clinical track full-time MD faculty within our academic medical center on July 1, 1996 (group 1), July 1, 2001 (group 2), and July 1, 2006 (group 3). Retention was tracked for 5 years post snapshot.

Gastric carcinoma with osteoclast-like giant cells.

Extraskeletal neoplasms with osteoclast-like giant cells are uncommon. These tumors are most frequently reported in the breast and pancreas, and are relatively rare in other sites. We report a case of primary gastric adenocarcinoma with an infiltrate of osteoclast-like giant cells.

Malignant mixed Müllerian tumor with rhabdoid features: a report of two cases and a review of the literature.

Rhabdoid tumors were originally described as a type of pediatric renal neoplasm that contains cells resembling rhabdomyoblasts but lacking muscle differentiation. Extrarenal rhabdoid tumors have since been reported in multiple anatomic sites in the pediatric and adult population. These tumors are characterized by an aggressive clinical course, resistance to treatment, and a rapidly fatal outcome.
